在這篇論文中提出一個創新架構應用在薄膜液晶顯示器之源極驅動器，此架構可以在低成本考量下達到高解析度顯示品質。
為了達到高解析度顯示品質，數位類比轉換器需要設計到十位元的解析度，但是往往會因為電路架構太龐大而導致成本大增；本篇論文提出的兩級電阻式數位類比轉換器是利用源極隨偶器來取代傳統架構的兩個緩衝器；且由於源極隨偶器的面積非常節省，所以可以讓成本大幅下降。
在內文中會介紹此電路的實現方法及考量，最後附上本論文使用TSMC 0.18UM 1P6M技術設計和晶片量測結果，經過10個通道量測資料整理下， DNL及INL分別為0.66 LSB/0.65 LSB，且此轉換器以全擺幅為輸出範圍的量測環境下的穩定時間約為4.8μS，是可以應用在大尺寸液晶顯示器上的規格。

In this thesis, a novel architecture applied in TFT-LCD source driver is proposed. This study can implement high resolution demand with low cost.
For higher resolution quality, 10-bit DAC is necessary but larger size and larger cost will be sacrificed. This architecture replace buffers in conventional circuit by using source follower and two-stage resister. Because of impact area of source follower ,a lot of cost can be saved.
This paper will introduce about how to realize this circuit and all the consideration. In the end of this paper, TSMC 0.18UM 1P6M technology is discussed with design flow and measurement results. The measurement results of 10-channel is DNL/INL with 0.66 LSB/0.65 LSB and 4.8μS settling time with full swing. It prove that this circuit is available in large size display monitor.
